KLDR time-delay fuses are designed to protect control transformers, solenoids and similar inductive components with high magnetizing currents during the first half-cycle. They provide excellent protection of motor branch circuits containing IEC or NEMA rated motor controllers or contactors. The KLDR Series fuses closely match most control power transformer characteristics, which permits them to be sized in accordance with the latest revisions of UL 508 (Industrial Control) and UL 845 (Motor Control Centers). Features & Benefits FEATURES Excellent short-circuit protection Rejection feature Current-limiting BENEFITS Improves safety through faster response to fault currents Restricts fault currents to provide high degree of circuit protection Prevents use of fuses with lower interrupting ratings or voltage when used with corresponding fuse holders Applications Transformer Protection Specifications Voltage Rating Ac: 600 V Dc: 300 V Amperage Rating 1/10–30 A Interrupting Ratings Ac:200,000 A rms symmetrical Dc: 20,000 A Material Body: Melamine Caps: Nickel-plated Bronze Fuse Weight .019 lb (8.62g) Approvals Ac: Standard 248-4, Class CC Dc: Littelfuse self-certified Environmental RoHS Compliant Country of Origin Mexico
